This came to me when we were trying to exploit the maximum out of parallelism factor in our storm topology. While going through the docs and understanding storm, I had in mind that we should increase the parallelism factor to get more throughput out of storm.

We had a sample storm topology which was using a kafka spout for its input feed. But after trying to increase the parallelism factor more than 1, we dint get a much of gain in throughput from out storm execution.
